A Study on the Performance of Crossflow Flat-Plate membrane Extractions
The effects of recycle on membrane extraction through a cross-flowrectangular module
have been studied both theoretically andexperimentally. Theoretical analysis of mass
transfer in cross-flowdevice with and without recycle was analogous to heat transfer
incross-flow heat exchangers. Experiments were carried out with the useof a membrane
sheet made of microporous polypropylene as a permeablebarrier to extract acetic acid from
aqueous solution by methylisobutyl ketone. Theoretical predictions are in agreement with
theexperimental results. Contrast a device without recycle, improvementin mass transfer is
achievable if cross-flow membrane extraction isoperated in a device of same size with
recycle which provides theincrease of fluid velocity, resulting in reduction of
mass-transferresistance.
